Name of the national road.

North Bridgeway is not an original part of Alabang-Zapote Road, or Route 411. The original part is a curved alignment between Filinvest Avenue and North Bridgeway, that is removed after the completion of Skyway Stage 2 in 2012, whose entrance/exit ramp required the realignment of Alabang-Zapote Road to use the ramp service roads which intersect North Bridgeway instead.
